CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser.No. 62/054,495, filed on Sep. 24, 2014, entitled Universal Enclosure forOptical Network and Circuit, the prior application is herewithincorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The present invention is a portable switching direct current voltagepower supply used at least in the telecommunications industry wherelow-voltage direct current devices require a switching power supply tostep down the voltage from a standard one hundred ten (110) voltalternating current, or other voltage source, to 12 volt direct-current,or other desired step down voltage. Additionally these devices useinterruptible power backup systems so that in the event of a powerfailure they continue to operate in order to provide continuedtelecommunication services or other services from the respective devicesto the public.

FIELD OF THE INVENTION

The present invention is directed to offer new efficiencies in the fieldof telecommunications for size, scalabilty and functionality by allowingan end user the capability to install anywhere within the premise as awall mount, desktop mount or floor mount, as well as allow for astand-alone power supply or scalable uninterruptable power supply withoptional stackable Li Ion (lithium ion) battery packs for customizedbattery backup availability.

The provided solution is the first to integrate a network solution toboth provide a universal housing for a telecommunication's CustomerPremise Equipment (CPE) device and also incorporate a switching Vdc(direct current voltage) power supply with optional battery packsutilizing lithium chemistry.

The provided solution offers alarm communication to the accepting CPEdevice and intelligent push button Vdc disconnection to the CPE in orderto reset Vdc power to the CPE device rather than disconnecting cables orremoving the battery pack to reset Vdc (output) power.

The switching Vdc power supply allows for attachment of one or multipleexterior attachable, removable and replaceable Li Ion battery pack(s)(also referred to herein as stackable) protecting the end user fromtraditional short circuit connections or crossing terminal wires duringinstallation.

The switching Vdc power supply offers the only portable solutionutilizing an attachable/removable battery pack comprised of a lithiumchemistry power supply.

The universal enclosure is the only CPE device all-in-one enclosure tooffer movable components that allow multiple manufactured CPE devicesthe ability to fit into the CPE device cavity of the enclosure and fitsecurely as well as house the custom switching Vdc power supply withoptional attached Li Ion battery pack and ability to store and protectmultiple input and output premise cables. The universal enclosure isalso the only CPE device enclosure to offer a cavity designedspecifically for a switching Vdc power supply and optional attached LiIon battery pack, whereas all past solutions must use a detachedswitching Vdc power supply and installed sealed lead acid (SLA) battery,mounted separately from the CPE device and/or enclosure. All togetherthe universal enclosure is the first to offer installation of variousmanufactured CPE devices, fiber and cable management, and switching Vdcpower supply and optional attached Li Ion battery pack all in oneenclosure with no exposed wiring tying the switching Vdc power supplyand optional attached Li Ion battery pack to the CPE device, whenprotective cover is installed.

The switching Vdc power supply is also unique by offering push buttonreset Vdc power and alarm communications to the CPE device. Theuniversal enclosure provides a convenience access door to initiate resetand alarm silence functions on the switching Vdc power supply.

DESCRIPTION OF THE RELATED ART

Traditional products include installation of CPE device with or withoutthe device housing and offers no universal movement unspecific to theindividually manufactured CPE device.
